This can be established from the convergent expansion (REF ) about \( z=\infty \)  using (REF ) or
computing the Laplace transform of (REF ) with the assistance of [1]} assuming \( \Re (z)>0 \) .
Therefore we note the M-continued fraction form
\(\frac{1}{L_{\gamma }(z)}= z + \hbox{\huge $\mathrm {K}$}\)
